Answer:
131 degrees
Step-by-step explanation:
When you take all parts of the circle and add them up, you are given 31y-12.
When you set 31y-12 to 360 (31y-12=360), you can solve for y and plug it in to all variables of the circle.
31y-12=360
Add 12 to both sides to cancel it out from the left.
31y=372
Divide 31 on both sides to cancel out and leave y on the left.
y=372/31
y=12
Now, plug 12 in to each variable. 54+77=131 degrees
Answer:
i. 818.18
ii. 940.9
Step-by-step explanation:
SP = 900
or, CP + 10% of CP = 900
or, CP + 10/100 × CP = 900
or, 110CP = 90000
or, CP = 90000/110
CP = 818.18
for profit= 15%
SP = 9000/11 + 15% of 9000/11
= 940.9
Answer:
Step-by-step explanation: To find a nonlinear equation, the degree of the linear equation must be 0 or 1 each from its variables.
As we see here the degree of the variable is 1, so y is 1. But the degree of the variables in the equation violates the linear equation definition. Since it does that, it's not counted as a linear equation.
Therefore, is not a linear equation.
Answer:
Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.
Step-by-step explanation:
What is sine? The sine of an angle x is the length of the opposite side.
What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
What is tangent? The tangent of an angle is the length of the opposite side
Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.
Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
= unit -----------------(1)
and, the power developed by the 2nd crane,
= unit ------------------(2)
So, we get that,
So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
